Cat Invaders Class Tier List

Classes in Cat Invaders are the long-term identity of a run. Weapons still do the killing — see the weapon tier list — but a Medic in a 12-player lobby is a different game from six Knights arguing over a chicken leg. This list ranks classes for solo wave pushing and online co-op separately where it matters.

Unlocks mix shop Gold, playtime, and the day-7 Alchemist daily. Codes do not grant classes. If a thumbnail promised a free Ninja code, it lied; check the codes hub.

S tier

Snowman (solo)
AoE snowball is the cleanest answer to clumped spawns. Wave-100 routes already want you on splash; Snowman is that plan with a class sticker. Pair with aim assist from the controls page and the ranged shop path in upgrade priority.

Medic (co-op)
Someone will die on Floppa lasers. A revive is worth more than 8% extra melee. Medic should buy food early and stand off the beam. In solo, Medic is A at best because you cannot revive yourself in a useful way compared to just not dying.

A tier

Knight
Armor synergy. If you already planned regen plates for wave 50, Knight makes those plates a build instead of a panic buy. Weak if you never open the armor tab. Strong on beat Floppa when a teammate kites and you hold adds.

Ninja
Players ask how to grind it, which is a signal. Mobility and burst help when lanes get sticky. Not the first unlock; do not stall Getting Started waiting for it.

B tier

Alchemist
Locked behind seven daily claims, so most of the player base is not on it during the hour they need help. The kit is a support/hybrid fantasy. Once you own it, treat it as A if you like the abilities; the rank here is mostly about access. Do not skip a week of Golden Weekend farming just to stare at the daily board.

Engineer (Version 1.1)
Turrets are extra barrels, not a replacement for splash. A-tier in co-op if someone actually places them. B-tier if you skipped ranged to afford the class.

Grenade / throw kits
Clump damage is real. Boss HP bars are less impressed. Fine as a spicy solo, worse than Snowman for the same job.

Vampire / Necromancer / Builder
Named in Version 1.1 notes and player comments. Rank them with the job they play like (combat / solo summon / walls), not by drip. Move them when a kit consistently clears Floppa.

C tier

Unupgraded starter identity
Whatever you spawn as before you pick a real class. Finish the shop identity. Fashion is not a tier.

Lobby modifiers

• Solo high waves — Snowman > Knight > everything that is not splash. See high waves.
• Duo with a friend — Medic + Snowman or Medic + Knight. One heal, one clear.
• Full 18 — at least one Medic. Extra Knights without food is a wipe with extra footsteps.
• Boss hunt night — Knight or Medic. Snowman still DPS.

Role loadouts: player builds. Lore-free kit talk: player classes.

Common ranking mistakes

Ranking a class by how it looks in a thumbnail with a minigun. The minigun is a weapon, not a class. Ranking Alchemist S because it is rare. Rarity is a daily gate. Ranking Medic D because you play solo. Then play solo and stop ranking Medic.

Patch notes that shuffle abilities will be noted on the updates hub. Until a written kit change, splash and healing keep winning.

If two classes feel equal in your hands, pick the one whose shop path you already funded. A funded B-tier beats an S-tier you cannot afford. That is the whole game hiding inside a letter.
